This is not a book aimed at Christians, but at fellow atheists. He deconstructs the myth of Jesus and how Christianity came to be the world’s biggest religion and how some of it’s teachings (especially those of Paul) may have come to be. Without Emperor Constantine, Christianity would have died or been an obscure sect. It explains the evils of monotheism. It is not so much about why there is no god as what evil people get up to in the name of god.
